Said end portion is ofthe usual yoke form .having upper and lower iv'ot jaws 15, 16, fOlmGdWlthalined ori cetwhich provide journal bearings *for tlie ai';eres'aidupper and lower trunnions i0, 11 of the head or shell 7. Each of saidjaws 15, 16., are of the usual two-part tormatiomshown in Fig. 2, topermit of assemblage Ofilllfi parts.

'17 designates a gland member having an annular huh portion slidin'glyfitting an annular rim portion 18 of the axle frame 14,

and adjustable thereon by a screwleeve 19, as shown in Fig.1. In thepresent improve- -ment said hub portion ot' the gland member 17 isformed witha pair'ot integral curved I wings 20, arranged in ahorizontal plane and adapted to closely fit the globular surface ofthehead or shell 7 to prevent leakage of the lubricant through theelongated orifice 12 of said head or shell 7 And to such end the bearingfaceof said wings 20 will be that the axes oi its different pivot pinsare p l on a plane common to the axes of the trim nions'lO, l1,aforesaid, and are adjusted to, and maintained in such position by meanshereinafter described.

The aforesaid'driving shaft section has the usual bearing in an internaljournal bushing of the axle housing 14, while the aforesaid driven shaftsection 23 extends through the axial bore of the axle skein or arbor andat its outer endis provided with a nod head 25, the perimeter of whichis formed with projections or lugs :26, for operative engagement withcomplementary recesses in the interior of the outer end. of the wheelhub 52, in manner substantially similar to that described and claimed inmy aforesaid prior Patent No. 926,313 and in said patented construction,said connection is covered bythe usual hub cap 2-7, as

shown.

In the present improvement n'iaterial features in the above describedhub and shaft connection (5011518138 follows:

29 des1gnates an axially arranged abutment screw, screwing through thehub cap 27 aforesaid, and adapted to eii'ect a longitudinal adJustmentof the driven shaft sect1on23 and the associated universal coupling 2%into the before described relation to the trunnions 1O, 11, aforesaid,as the parts become worn by continued use, as

well as in an initial assemblage of the Wrasse fit the globular cavityof the fixedly associated enlarged head 3 and head or shell 7 aforesaid,and provided with diametrically opposite orifices corresponding with thebore of the axle sirein or arbor l, and with the horizontally elongatedorifice of the head or shell 7, respectively, the first inenv tionedorifice being of a horizontally elongated form to permit of the requiredpivotal movement of the shell 30 in a horizontal plane in actual use.

31 designates a packing recess or gland at the margin of the elongatedorifice, just described, and adapted to prevent leakage of lubricanttron the interior of the shell 30 at such point.

32 designatesa cylindrical neck or 9X tension on the holding shell 30aforesaid, formed to fit the bore of the annular rim portionlS of thefixed axle frame or lions ing 1% aforesaid, to aid in maintaining theholdingshell 30 in proper position, and by its extension past the jointor seam between the gland member: 17 and the rim portion 18 aforesaid,prevent any leakage of lubricant at such point.

designates a bearing collar adjus tably attached to the outer end of theupper trunnion 10, by a headed screw 3i, preferably of the tubular typeshown and for the purpose hereinafter stated. Said collar 33 is adaptedto have bearing upon the top surface of the upper jaw 15 of the yoke ofthe axle housing 14 aforesaid, to assist in maintaining the trunnionsl0, 11 in proper position, and resist vertical downward thrusts inactual use. 7 l

- 35 designates a hearing collar adjustably attached to the outer endotthe. lower trunnion ll, by a headed screw 36, adapted to have bearingupon the under surface of the lower j aw 16, of the yoke of the axlehousing 15 aforesaid, to cooperate withthe collar atoresaii'l, inmaintaining the trunnions 10, 11, in proper position, and resistvertical thrusts thereon in actual use. The headed screw 36 aforesaid,is preferably of the expansion lock typeshown, so as to be capable ofbeing locked at its desired adjust ment'.

In the modified structure shown in Fig. 4, the lower trunnion 3.1 isprovided with a screw-threaded extension 37, which passes through acollar 35, similar in arrangement, to the collar 35 above described.Said extension 37 receives a pair of locking nuts 38 adapted to drawsaid trunnion 11 in a downward direction, and resist any verticalstresses tending to move said trunnion and associated parts eitherupwardlv or downweirdly.

39 designates a headed screw-threaded tubular stem fitting an axial borein the upper trunnion 10- aforesaid, and adapted to its ice
